1. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. Match the abbreviation with the correct definition:

• A. bid: twice a day
• B. tid: three times a day
• C. ac: before meals
• D. pc: after meals

Correct answer: C

Rationale: The abbreviation 'ac' stands for 'ante cibum,' which means 'before meals.' 'Bid' means twice a day. 'Tid' means three times a day, and 'pc' means after meals. When interpreting medical abbreviations, it is crucial to understand their precise meanings to ensure accurate communication and patient care.

3. An adult's blood pressure reads 40/20. You place the patient in a Trendelenberg position before rechecking the blood pressure. What actions will you take to position the patient correctly?

• A. lower the head of the bed and raise the foot of the bed
• B. raise the head of the bed up to about 60 to 75 degrees
• C. raise the head of the bed up to about 75 to 90 degrees
• D. raise the siderails and place the bed in the high position

Correct answer: A

Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.

4. The nurse supervises unlicensed assistive personnel (UAP) who are providing care for a patient with right lower lobe pneumonia. The nurse should intervene if which action by UAP is observed?

• A. UAP splint the patient's chest during coughing.
• B. UAP assist the patient to ambulate to the bathroom.
• C. UAP help the patient to a bedside chair for meals.
• D. UAP lower the head of the patient's bed to 15 degrees.

Correct answer: D

Rationale: The correct action for the nurse to intervene in is when the UAP lowers the head of the patient's bed to 15 degrees. This position can decrease ventilation in a patient with pneumonia, potentially worsening their condition. Choices B and C involve assisting the patient with activities of daily living and promoting mobility, which are appropriate for the patient's care. Choice A, splinting the patient's chest during coughing, can help the patient manage coughing effectively, which is also appropriate for a patient with pneumonia.

5. When would chest thrusts be performed in an emergency situation?

• A. When performing CPR to initiate cardiovascular circulation.
• B. When assessing responsiveness of an unconscious patient.
• C. When assisting a pregnant woman who is choking.
• D. None of the above examples indicate the need for chest thrusts.

Correct answer: C

Rationale: In the scenario of an emergency where a pregnant woman is choking, chest thrusts are performed to clear the airway obstruction. This technique is used instead of abdominal thrusts to avoid potential harm to the fetus. While chest thrusts are not as effective as abdominal thrusts in clearing obstructions, they are the preferred method in this specific situation. Choices A and B are incorrect as chest thrusts are not typically performed during CPR to initiate cardiovascular circulation or when assessing responsiveness of an unconscious patient. Choice D is incorrect as chest thrusts are indeed warranted when assisting a pregnant woman who is choking.
